Write the equation of the line in Slope-Intercept form.
Answers
Answer:
Y=-2/3+4
Step-by-step explanation:
The slope of the equation can be solved with
2-4/3-0 y2-y1 divide by x2-x1 which gives 3/2 and the y intercept the point at which the slope hits the y intercept which is 4. Also the slope is negative as it’s pointed downwards.
Getting the slope:
m=[tex](y_1 - y_2 )/(x_1 - x_2)[/tex]
Using this formula, the slope is calculated to be -2/3
To find intercept, plug in a point value into equation and solve.
Intercept = 4
Total equation: y=-2/3x + 4

Step-by-step explanation:
Assuming you require to factor the expression
x² - 15x + 36
Consider the factors of the constant term (+ 36) which sum to give the coefficient of the x- term (- 15)
The factors are - 3 and - 12, since

20% of a is 11 what is a
Answers
Answer: 20% of 11 is 2.2
Step-by-step explanation:
Answer:
55
Step-by-step explanation:
To solve this set up a proportion. This proportion should be in part/whole form. This means to divide the part (aka 11) by the whole (aka the variable), additionally, 20% can be made into a fraction by dividing it by 100. So the proportion is [tex]\frac{20}{100} =\frac{11}{x}[/tex]. Then, cross multiply. Once this is done the new equation is [tex]20x=1100[/tex]. Next, divide both sides by 20. This gives you [tex]x=55[/tex], therefore 11 is 20% of 55.

NEED HELP ASAP!The maker of a cell phone screen protector would like to estimate the proportion of customers who file a warranty claim. To do so, they select a random sample of 200 customers and determine that the 96% confidence interval for the true proportion of customers who file a warranty claim to be 0.15 to 0.28. Which of the following can be accounted for by the margin of error of this interval?
response bias
nonresponse bias
sampling variation
undercoverage bias
Answers
Answer: sampling variation
Step-by-step explanation: took the quiz
The margin of error is given by the sampling variation of the proportion of customers
What is simple random sampling ( SRS )?The most accurate type of probability sampling is random sampling. Each person in a population has an equal probability of getting selected for the sample thanks to this method of sampling.
This kind of sampling is perfect for highly controlled investigations where it is unacceptable to have human bias in the selection of the sample.
Each sampling unit in a population has an equal probability of being included in the sample when using simple random sampling (SRS). As a result, each potential sample has an equal probability of being chosen.
Given data ,
Let the margin of error be represented as A
where the value of A is
The confident interval is = 96 %
And , the value of sample is of 200 customers
where the warranty claims from 0.15 to 0.28
So , the cell phone screen protector maker can be 96% confident that the interval from 0.15 to 0.28 captures true proportion of customers who file a warranty claim
Therefore , it is a sampling variation
Hence , the situation is a sample variation

Suppose the height of a triangle is tripled. How does this affect the area of the triangle? Explain
Answers
Answer:
A' = 3A
Step-by-step explanation:
The area of a triangle is given by :
[tex]A=\dfrac{1}{2}\times b\times h[/tex]
Where
b is base and h is height
If height is tripled, h' = 3h
New area,
[tex]A'=\dfrac{1}{2}\times b\times h'\\\\=\dfrac{1}{2}\times b\times 3h\\\\=3\times \dfrac{1}{2}\times b\times h\\\\=3A[/tex]
So, the new area becomes 3 times the initial area.

Out of the 90 customers at Eva's boutique35 wore a size extra-large. What is the probability that a randomly selected customer wore a size extra-large? Write your answer as a fraction or whole number. P(extra - large) =
Answers
Answer: 7/18
Step-by-step explanation:
Number of customers at Eva's boutique = 90
Number of customers who wore a size extra-large = 35
The probability that a randomly selected customer wore a size extra-large will be:
= Number of customers who wore a size extra-large / Number of customers at Eva's boutique
= 35 / 90
= 7/18
Therefore, the probability that a randomly selected customer wore a size extra large is 7/18.

Consider the following system of equations.
3x + 5y = 18
6x − 5y = 20
Decide which procedures eliminate the x variable and which eliminate the y variable. Drag and drop each procedure that will eliminate one of the variables into the appropriate category.
Subtract the second equation from the first equation.
Add the first and second equations. Multiply the first equation by −2; then add the two equations.
Divide the second equation by −2; then add the two equations. Subtract the first equation from the second equation.
Multiply the first equation by 2 then add the two equations.
Eliminate x Eliminate y
Answers
Answer:
Option B
On adding the first and second equations y can be eliminated
Step-by-step explanation:
The two equations are as follows
3x + 5y = 18 -- Eq (1)
6x − 5y = 20 -- Eq (2)
Adding equation 1 and 2, we get -
3x + 6x + 5y -5y = 18
9x = 18
x = 2
y = (18-3*2)/5
y = 12/5 = 2.4
